New pc gaming for emualtors: which is the best cpu/gpu?

Hi

i would like to buy a mini-itx in order to use it with my tv fullHD 46" with all the emualtors, CEMU included. Do you think that this could be ok in order to play CEMU with its best performance adn effects at maximum level? is it better i7 8700 or Ryzen 2700X?

Do you think that with this pc i will be able to play CEMU with top performance also with a 4K tv if i will set the output of the emualtor to 1080p instead of 4k? I think that if i want to play it at 4K with maximum effect i need a more powerful pc...

Since you just said two LGA 1151 motherboards I assume you're going with intel. 2700x in my opinion has more applications, but single core performance goes to the intel. If you're looking to play at 4k, presumably at 30fps like the switch or wii u I think a 1070 will get you where you're going. Just not very familiar with the performance of the mini. Look up benchmarks of the card you're looking at, look at youtube for people playing Cemu with the components you want to go with. Can't go wrong there.
8gb should be plenty for the emulator

Well yes, for emulation maybe. But 2700x has much better multicore performance if you have any kind of workflow or multitask a lot. Problem is I've never seen an 8700, only the 8700k. I know an 8700k will get you 4k at least 30fps no problem, but I couldn't tell you confidently of the 8700 even though they should technically be within a stones throw in performance

well, i don't have currently a 4K tv so i think that this pc could use CEMU emulation at its best performance, isn't it?
If i will use in the future a 4K new tv, i don't know if this pc can run CEMU in 4K at ist best performance..

ah ok i can test it even if i don't have yet a 4k tv simply choosing the 4K options in the emulators, good!

You get benefits on a 1080p (or other lower than 4K) monitor if you use 4K on Cemu. That is because it effectively does supersampling antialiasing which is the best quality antialiasing method that exists.

What supersampling antialiasing does is to first render normally at very high resolution and then scale down to the monitor. That is effectively identical to Cemu rendering at 4K textures.

i have another question: if i buy a notebook instead of a pc desktop, with same specifics i have written above, do you think that a cpu like i7 8750H or i7 8850H, are enough for CEMU with maximum performance (even if these 2 cpus aren't good like the i7 8700 of a desktop pc)?
thank you
